To all whom it lmoz/ 2,1 concern: )Beit-known that i, NATHAN E. MORRIS,

- Ur., a citizenv of the United States, and a resident of Murfreesboro,

in the county oi Rutherford and State of Tennessee have u made certain new and useful Improvements A1n CaslrRegistersv and indicators, oi which the/following is a specification.

'My invention is an improvement in cash `registers and indicators and has'for an object .among othersto provide means whereby the amount of change will be indicated either preferably both front and back, a minuend,y

alone, as for'instance in making-change, or together with the amount oi the sale, or in other words, a machine which will indicate,

a subtrahend, (the amount. of the saie) and a remainder, the'amount Aof the change, the

machine doing the subtracting.

In carrying out my invention and as important features therec.L` l rovide a machine jhaving a set of drums n icating the minuend va set 0i drums 11A-heating the subtrahend; and a set of drums indicating the remainder together with means whereby the remainder indicating fevices may becaused to move'in one direction in correspondence with the movement of the minuend indicating devices and means whereby the remainder indicating devices are caused' to move in the opposite direction by the ,movementof the subtrahend indicating devices and-I arrange the means for operating the -minuend indicating devices so in theirjoint `operation they may-move the minuend indicating devices in one direction rand then in the other to secure an accurate indication of the remainder.

With the foregoing and other objects Lin view, my invention-consists in certain novel constructions and combinations of arts as will be hereinafter described and claimed. v VIn the drawings-Figure l'is a iront elevation of the mac ine.

The counter eresie n shaft E Which gear l) meshes Witha gear F first five segmented and such Wheels J-to J4 fast upon the end of a shaft G, the latter being the main shaft of the machine. The `shafts E and G extend entirely across the machine tothe left side thereof.

The shaft G is provided near'its left end t with' a crank Q, see 3 and 7 which is connected by a pitman With the crank arm S on the rock shaft H Which extends entirely' across the machine. The shaft' G is given a 1 'completer revolution at each operation of 'the machine hy the handle A and the shaft H is 'thereby oscillated .through the crank connections-forward'and backward a little more than one-'third of a revolution in order tov secure the operation` of the '-subtrahend indicating devices subsequent to that of the 'minuend indicating devices'.

Loosely mounted-upon the shafting' at suitable dist-ancesware .five gear' tooth segments I, see Figs. 2l or 7, corresponding respectively to `the key `banks 6', 7, .8, 49, and l0, which keybanks Will in practice be letu tered. in black and the key banks 11, 12, 13 and 14 Wil-Lbe lettered in red or some other 'distinguishmg color.

vThe ,four'rack'pinions` or mutilated gears 05, (16,07, and C8, see Figs. 2 and Il, `drive the ,lo'ngitudinally .movable rack bars'D, D, D2 land D3. These rack bars are guided in their Alongitudinal movement by suitable guides C20 and' C21 Las shown, see Fig. 2, and operate to actuate'ithe upper or minuendA set or tier of drums', the keys of thekey banks .11', 12,

13 and'14, see "Fig. 1operati-ng respectively in connection jfWith the said vrack pinions being in practice lettered in red to aid the eye in locating them as before stated. ,The lgear'vvhe'elsJ, J', J2, J3 and J4 are meshed respectively' as before described with the finclusive are fixed respectively vto the righthand ends of sleeves j, j,'j2, js and y`4, see Fig. 3,- telescopicallyarranged and extend ing to theleft hand side'of` the machine. These sleeves y" tol 1'4 are carriedby the shaft 'E and support at their'left hand ends the type arms V4 constituting." artsr of arecordv ing mechanism' similar to t -`.at/shown in the Patent N o. 580,378, before-referred' to. The

sleevesfj to i4 are free to rotate-upon theshaft E and y,upon `each other and' arejthus capable of independent-movement .It will i be noticed that ,the gearA '.vvheelJ, see Figs. '2

gear VWheel .5" meshesV with the wheel H5 .yvhich in turn meshes with the Wheel O3 having the pinion O4 fixed to its right hand side. This pinion O'4 meshes with the pinion O on the shaft L Which shaft is provided with the .pinion O which meshes directly With the gear attached to the side of the clerkindieating drum 15 arranged at the center of the middle tier. By this means the clerk indicating drum is operated in the use of the machine. The clerk indicating drums are arranged inpairs, sleeved together, one drum 16 indicating to the front of the machine and i 'the'other 15' indicating correspondingly to i the back of the machine. The pinion J meshes With the Wheel F, see Fig. 7 Which in turn meshes With'the Wheel H, the latter meshing IWith the Wheel O5 provided with a pinion O6 fixed to its right 'hand side. f This pinion OG meshes with a pinion. P on one end of a sleeve P mounted'loosely on the shaft L and rovided at its other end with a pinion Btw ich meshes With thegear ring connected with the drum for indicating the tens of dollars at the back of the machine. This drum 17 is connected by the sleeve18 with the drum 19 for indicating tens of doli ylars at the front of the machine.. The gear- J2 meshes with the gear F3 which in turn meshes with `the gear H7 Which meshes with a pinion O7 which is connected by a sleeve 20 to the drum 21 which indicates units of dollars atthetback of the machine. This indicator Wheel or drum 21 is connected by a sleeve 22 With its corresponding Wheel or drum 23 for indicating units of dollars yat the front of the machine.

By the described construction'it will be noticed l am able to arrange the drums 21, f

17,. 15,116, 19 and 23 in a compact form so they may be operated to serve their respective purposes in the operation of the maf chine. i l

The gear J3 meshes with the gear F4 Which vmeshes With the gear H8 Which meshes with the gear Os connected by` a sleeve -24`with the Wheel 25 which indicatestens of` cents at the front of the machine. This drum 25 is provided With a gear 26 which meshes With' a pinion 27 on a sleeve 28 mounted on a shaft 29 extending transversely across the back .of -the machine, said sleeve' having a pinionf30- which meshes With a gear.ixed to theside of the drum 31 .for indicating tensof cents at the back of the machine'.

The gear J4 meshes' with the jwtael` F5 which in turn meshes with the .Wheel Hg which meshes with the pinion'O connected by 'a 'sleevey 32 to the Wheel 33 indicating limits of cents 'at the 'front of the.` machine.'

For'indicating' units' of'cents at the back of provided With a' pinion-35 which meshes-With ist thejmachine I mesh the gearringc'onnected' Y a gear on the side of the drum or wheel 36 also the clerk in any particular` transaction. i

In order to indicate 100 dollars on the ininuend tier lwithoutl the necessity of a separate drum forn suoli purpose, I provide,

alongside of' the drum indicating tens of doll lars, what, for convenience of reference, I

term an extension indicating frame CS, seel Figs. 2, 4 and 7, the same co'nsistiiuY of an i arm 37 which isjournaled 'at its micdle on one of the sleeves supported lon the shaft E,

is moved in one direction by a spring 38;

whichl tends to hold -said indicator frame normally in neutral position. -At the opposite ends of the arm 37 I provide the curved y plates 39 corresponding to the segments of a wheel rim and arranged to show one at the front and the other at the back of the machine and properly inscribed with a 3 mark and the number 1 to complete the indication of 100 to 109 dollars ,and 99 cents in setting up amounts in excess of 99 dollars and 99 cents. Normally the spring 38 see Fig. 7 holds the extension frame CS in such position that these plates 39 will show simply $5 marks at both the iront and rear of the machine and in order to nieve this extension frame one step to expose its figure 1 I provide for operating it by the rack bar D, the latterl being provided with a pin C9 see Fig. 7 arranged to engage the arm CS when said rack bar has been moved to such position as to move the ininuend indicator Wheel showing tens of dollars through nine-tenths of its revolution so that if the said bar D be moved one stepI further it vwill move the indicating frame C8 to sucli'an extent as to expose its numeral 1 in connection with the numerals that may be indicated on the indicator drums of the minuend tier Then when the rack bar-returns to its normal position the spring 38 will automatically readjust the extension indicator trame as desired. It Will be under'- stood that I am able to operate the extension indicator trame in this manner by providing ten instead of nine keys in the bank 11 of keys see Fig. '1 thus avoiding the necessity of a separate bank of keys and cooperating mechanism for enabling me to set up the one indication in the hundred of dollar'line.

The rack pinions C5, C6, C7 and Ca supported by and free to rotate on the shaft H mesh with and drive the rack bars'D, D', D2, and D3, see Fig. 2.

The rack bai' D operates to indicate the tens and hundreds-'of dollars on the upper or ininuend tier and also operates to effect a movement. ofthe tens of dollars indicator of the indicator of the upper on the remaindertier corresp ding to that 2 and 7. The rack bar D o1 fates to indi-I cate the units of dollars on the upper or minuend tier and also operates to effect a corresponding movement of the units of dollars indicator on the remainder-tier. The rack bars D2 and D3 likewise operate respectively on the indicator drums for tens and units of cents on the upper or minueiid tier and the lower orremainder tier.

Tlie'rackbai' D drives the pinion H oiE the lower tier and the pinion P3 oi' the upper tier, such pinion being fixed to the side of the indicator wheel. 40 vwhich indicates tens of dollars at the front of the upper tier.

The pinion C see Fig. 2 drives the rackv D which meshes'with and, drives the pinion H2 of the lower tier and also the pinion P4 fixed to the left side of wheel 41 indicating units of dollars at the front'oi the upper tier. The pinion C7 drives 'the rack-D2 which drives the pinion Hain the lower tiel' and the pinion Pi fixed to the indicator wheel 42 indicating ltens of cents at the front of the upper tier. The pinion C8 drives the rack D3 which drives bars act alone while in securing the proper-A ker, see Figs,4

indication of thereinainder on the lower tier .4 they act in con] uncti on with the subtrahend indicating devices, the indicating drums or wheelsof the remainder series vor tier being moved first in one direction to an extent corresponding to the amount handed vin by the purchaser to give the niinuend on the said drums and then being moved in the reverse direction to an extent equal to the amount ofthe purchase or the subtraliend in order to secure the subtraction, it being understood that in securing a perfect subtraction it will be necessary in some instances to bring into play thecarrying devices from units to tens and from tens to hundreds etc., as will be described hereinafter.

The remainder indicating devices include the Wheels or drums 44 to 51 inclusive. The

itis

drums 44 and '45 indicate tens of dollars on l respectively the front and back ofthe machine, the drums 46 and 47 indicate respecltivelyfunits of dollars on the front and back instead of positively operating the drums in one fdirection operate to effect such move-` J1", and The pinion meshes with the pinion J which is fixed to fthe gear A5 Which meshe with the pinion P5 on the shaft Whichgfshaft is also provided With-the pinion I4 meshing with the drum 45 Which indi catestens of Adollars at the back of the machine. The drum 44 for indicating. tens of dol-lars on the Ifront of the machine is also drjvenfrom the shaft L2 by means of a pinion e Y, J5 causing it to rotate in onedirection.

P5 soerthat the said shaft Lzoperates both drums 44 and^45 being in turn driven from thegear J5 which is loose on the shaft E and is actuatedv in onedirection by means of a spring b fixed `at one end to the gear J5 and at its opposite end to the frame of the ina-- chine thus givingtension to the said Wheel To limit themovement of the drums 44A and 45 by the action of the s ring b through the gearing connectionsbe ore described I provide in connection with the drum 44 the p inion H Which is providedl With a sleeve fitting Within the drum 44 and having at one end of said sleeve a disk 52 providing'a support for a tooth or spur c see Fig. -10 Which is abutted the lminuend on the minuend indicating deby a ylug aonthe side of the drum 44 and operates by the engagement of said lug a with the tooth or projection c to stop the movement of thel Wheel 44 by the action of the spring and to permit the said drum to move forward or follow the said tooth c as,

thesame is moved by the meshing of the rack bar DWith the pinionI-Iin the operation of setting up the minuend vas before described. By this means it Will be seen that as the rack 'bar I) moves thel pinion H forward it also moves or advances the tooth c so that the lug a on the frame 44 can follow up the tooth c to the full extent to which the said tooth is advanced during the 'operation of settirg up vices; e Atthe same time as the lug a'abuts the rear side of the tooth c there is nothing to interfere Withthe'revelrse movement of the I drum 441m adjusting the same back corre-v sponding e to the subtrahend in securing fthe,

This is effected ley-means of an'arm S9 on the sha-ft G2 arranged-at its free end to engage the peri ,hery of a cam R6 see Fig. 8 on the shaft G an having a de ressed' portion a5 in which the free endof tie arm S5 rides at-such time as it is desired for thelateral arm X5 of the pawl holding arm G5 to rest upon its plate C4. At other times the free end of the arm S9 riding on the outer surface of the cam It will be so operated as to tilt the shaft G2 in such man-l ner as to hold the arm G5 with its lateral pin or armX5 clear ofthe plate Cito relieve all friction between said parts. vIt will also be understood that the cam R5 operates to move the awl holding arm G5 outward to draw its pin from beneath the plate C4 in the readjustment of the parts inthe o eration of the machine, 'it being understoo that the outward movement of the arm G5 will free the pa'wl S8 from engagement with its ratchet wheel V5.

It will be understood that in referring to the wheel in the units train and the wheel in the tens train of any articular series, I do not desire to be limite to the series ranging from 1 to 10, it being understood that I employ the same 'mechanism for carrying from tens to hundreds, and from hundreds to thousands if necessarvto an unlimited extent and I desire in referring 4to the wheel r gears J, J", J?, J3 and J4 on the shaft E, which v said gears operate them'subtrahend indicating 'devlces-asy before described;

the true remainder, but just at this eriod the carrying devicesbefore described 'begin to' act as follows.

Thezcam R see Fig. 8 has in operation revolved s o that Ythe free end of the. arm S9 is now moving in the depression-10,2, allowing the lshaft \G2tolv rotate slightly forward, pern/iittinggthe G5 to fall forward until its arm at presses against ,theV iiange C4. `Now this flange has passed from under the arm m5 which it always does when its corresp onding indicatorwheel passes from Zero toward 9, `otherwise there would be no need of carrying, and the pawl SS will engage the ratchet wheel V5 causing the gear to 'which it is attached to move sufl''cientl'y tio-cause its indicator wheel of the lower tier to move through one space as the cam T4 raises the free end of the pawl carrying plate V8.v The lower or lremainder tie'rwill now indicate 9521.44, the
